Introduction
Symbol Technologies’ Vehicular Radio Computers (VRC) 4000
series are PC-compatible computers ruggedized to withstand
the physical shock and vibration extremes of harsh industrial
environments. All VRC systems provide a touchscreen, full
VGA display (either electroluminescent or color LCD), multiple
network options, and full I/O capability. Each VRC system is
fullyPC-compatiblewiththeMS-DOSVersions3.3through6.22,
Windows 3.1, Windows 95, and Windows NT operating
systems. There are two versions of the VRC: the VRC 4000 and
the VRC 4040. Each of these versions are available with options
such as additional memory, operating systems, and network
configurations.
VRC 4000
The VRC 4000 is designed for fixed-mount applications. It is
powered by a standard 110 VAC outlet via a plug-in power
supply. It is hard-wired into the local area network (LAN).
Standard Ethernet or Token Ring hard-wired LAN connections
are supported.
VRC 4040
The VRC 4040 is designed for vehicular-mounted applications
such as those on forklifts, hysters, and motorized pallets. It is
powered from the vehicle’s electrical system (battery) through a
choice of two power converters. It uses Symbol’s Spectrum24®
2.4 GHz spread-spectrum radio link to communicate with radio
frequency (RF) networkaccess points hard-wired into the LAN.
Antenna options include patch and ‘rubber duck’ types.

Set-Up
To set up your equipment, first unpack your terminal and
accessories, and ensure that the parts shipped match the parts
ordered. Keep the shipping container and packing material in
case you need to return your computer for repair at a later date.
The VRC is factory-equipped with a network interface and the
appropriate network software for communicating with the
network. The network ports on the VRC use different connectors
for each type of network. For Token Ring connections, a DB9
connector is used. For Ethernet connections, an RJ-45 connector
is used. For wireless network communications, an FCC
mandated, non-standard RF antenna connector is provided.
Note: The VRC 4040 uses Spectrum24 2.4 GHz spread-
spectrum radio link to communicate with (RF) net-
work access points hard-wired into the LAN. These
access points must be set up before the terminal can
communicate with the host. Refer to the Access Point
User Documentation for detailed instructions on set-
ting up the access points.
Mounting the Bracket Assemblies
The VRC 4000 can be mounted almost anywhere that is
convenient to the operator. The mounting location must be near
a standard 110 VAC electrical outlet, and there must be sufficient
space below the unit for cable access to the rear panel, which
faces downward when the unit is wall-mounted. Secure the
mounting bracket to a wall prior to attaching the VRC 4000 to
the bracket.
The VRC 4040 mounts to a forklift or other vehicle with a custom
bracket assembly. Operating power is obtained from a DC
power converter that attaches to the vehicle’s electrical system

5
via an access cord. Installation of the VRC 4040 requires
mounting the bracket assembly, installing the DC power
converter, andattachingthe accesscordtothevehicle’s electrical
system. Caution
For proper operation on electric fork lifts, the VRC must be
isolated from the chassis. Damage to terminal could result.
The three types of mounting bracket assemblies are:
• universal mounting assembly
• hyster mounting assembly
• crown mounting assembly.

Providing Power to the VRC 4000
Power is provided to the VRC 4000 terminal via a locking DC-
power adapter, as illustrated below:
All cable connections should be made to the VRC 4000 before
the systemis powered up. Since there isno ON/OFF switch, the
VRC 4000 powers up as soon as the power supply connections
are completed and the power supply is plugged in to the 110
VAC electrical outlet.
Providing Power to the VRC 4040
Power is provided to the VRC 4040 via a DC power converter (12
V or 24-48V) that is connected to the vehicle’s battery. The DC
power converter mounts to a steel surface on the vehicle via
magnetic feet. Locate the converter so as not to interfere with
either moving parts on the vehicle or the operator’s vision. Be
certain that the power cable from the DC power converter can
reach the mating connector on the VRC 4040.
The access cable should be connected to the vehicle’s electrical
system, at the point that provides power at all times and that is

12
filtered and fused. Never connect the accesscable directly to the
battery terminals. Possible connection points are at the horn,
lights (feed), or ignition switch (feed).
24-48 V Power Converter
The electrical harness access cable for the 24-48 V Power
converter has two leads at one end which are permanently
wired into the vehicle’s electrical system. The other end of the
cable has a circular 2-pin connector with rubber boot that mates
with a similar connector on the DC power converter’s power
input cable.
Caution
On some older electric fork lifts, it might be necessary to in-
stall a 4 amp, 25 mhy filter choke (STANCOR p/n C-2686
or equivalent) in series with the positive lead to prevent
motor transients from interfering with the terminal.
The black harness wire is connected to apositive voltagesource.
The white harness wire is connected to the negative voltage
source. The booted connector end of the cable should be
accessible for convenient attachment to the DC power converter.
Make sure that the DC power converter ON/OFF switch is in
the OFF position. Once the access cable is wired to the electrical
system, mate the connectors on the access cable and the DC
power converter power input cable. All cable connections must
be completed before applying power to the VRC 4040.
12 V Power Converter
The electrical harness access cable for the 12 V power converter
has three leads at one end which are permanently wired into the
vehicle’s electrical system. The leads are white and black, plus a
third lead that is either shield braid or green. The other end of
the cable has a circular 3-pin connector with rubber boot that

13
mates with a similar connector on the DC power converter’s
power input cable.
The black harness wire is connected to a positive voltage source.
The white harness wire is connected to a negative voltage
source. The green or braided lead is connected to chassis
ground. The booted connector end of the cable should be
accessible for convenient attachment to the DC power converter.
Make sure the DC power converter ON/OFF switch is in the
OFF position. Once the access cable is wired to the electrical
system, mate the connectors on the access cable and the DC
power converter power input cable. All cable connections must
be completed before applying power to the VRC 4040.
Maintenance
The VRC is designed to operate normally in industrial
environments which may contain high levels of airborne
contaminants including dirt and smoke. Periodic cleaningof the
VRC is recommended to remove build-up of foreign substances
on the case and touchscreen.
Before cleaning, remove power from the VRC. Wipe
accumulated dirt and dust from the case with a slightly
dampened cloth, paying particular attention to the angled edge
of the bezel. Clean the touchscreen with a commercial brand of
computer screen cleaner and a soft, damp cloth or compressed
air.
